For a lot of people, the IVF process can be a pretty stressful one in general. It is one of the methods a couple can use in order to possibly have a child, but it is not always going to work. It comes down to a lot of factors, and just waiting to see if the process works is stressful.
Most people who go with IVF are looking at one of the final options for them to turn to. If it does not work, many people end up going to adoption centers in order to possibly have a child. It can be a very stressful time, because there is really no way of knowing if something is going to work or not.
Additionally, it is not a very cheap thing to do if a person is trying to have a child. Many need to keep that in mind.
